HOOK.

Specification of Letters Patent.

Application filed January 2, 1914. Serial No. 810,054.

To all whom it may concern Be it known that we, MARK HEATON ROB- INSON and Lnsnrn HAMPTON ROBINSON, both subjects of the King of Great Britain, the former residing at Westminster, in the county of London, England, and the latter residing at Chiswick, in the county of London, England, have invented certain new and useful Improvements in Hooks, of which the following is a specification.

Our invention relates to improvements in hooks having a pivoted mousing adapted to open and close in the gap of the hook, and it is specially applicable to the hooks used for suspending boats from the davits of a ship.

The objects of our improvement are to construct a hook in which the mousing is independent of the width of the gap of the hook within ordinary strain limits, and to provide a hook in which the mousing gear is protected from damage by outside agencies as far as possible.

We attain these objects by the mechanism illustrated in the accompanying drawing, in

which Figure 1 is a side view partly in section showing the invention on a hollow backed hook; and Fig. 2 is an end view showing the invention applied to a solid hook.

In Fig. 1, A is the body of the hook; B is the mousing tumbler lying in the slot O, O, and pivoted loosely upon the pin D. The tumbler is shown in the mousing positi on, resting upon the bottom of the slot. Its arm or extension E projects through the back of the hook. When it is desired to unhook, the extremity of the arm E is pushed downward by a touch of the finger, into the position shown in dotted lines, with the effect of removing the mousing and leaving the hook open for unhooking. The tumbler is now retained by its own weight in the open position with the arm E resting upon the bottom of the slot as shown. When the extremity of the arm E is pushed upward beyond a certain point, the tumbler falls again into the moused position. In hooking-on, the mousing tumbler oifers no hindrance; it lifts to allow the ring to pass and then drops into its place again.

Copies of this patent may be obtained for Referring now to Fig. 2, the back of the hook A is solid, but is recessed on its sides at F, F, so as to form flat walls; the spindle D is passed through a hole in the hook and carries tumblers B, B said tumblers being fixedly secured thereto in any suitable manner. Firmly attached to the spindle also are milled ends G, G by which the spindle can be rotated, and the tumblers B, B being rotated therewith can be brought into the open or closed position by the milled ends Gr, G In either case the shoulders formed by the recess can be so shaped and placed as to limit the movement of the tumblers within the required limits.

What we claim as our invention is 1. The combination with a hook, of a mousing tumbler pivotally connected therewith for movement into and out of mousing position, and means at opposite sides of the pivot for yieldably holding the tumbler in either its mousing or non-mousing position.

2. The combination with a hook of a mousing tumbler pivotally connected therewith for movement into and out of mousing position, and means extending from opposite sides of the pivot for yieldably holding the tumbler in either its mousing or nonmousing position, said means including a finger piece whereby the tumbler may be rotated.

8. The combination with a hook, of a mousing tumbler pivotally connected therewith for movement into and out of mousing position, said tumbler being movable with its free end to either side of a vertical plane including its pivot, and means extending at each side of said plane adapted to yieldably hold the tumbler in either its mousing or non-mousing position, said means including a combined finger piece and stop operable to effect and restrict pivotal movement of the tumbler.

In testimony whereof, we have signed our names to this specification in the presence of two subscribing witnesses.
